Description
技术领域technical field
本发明涉及一种废旧干电池无害化处理技术，更具体的说，它涉及一种利用转底炉工艺处理废旧干电池的方法。The invention relates to a technology for harmless treatment of waste dry batteries, more specifically, it relates to a method for treating waste dry batteries using a rotary hearth furnace process.
背景技术Background technique
大量的废旧干电池不仅对环境造成严重污染，对人体健康造成危害，而且还导致了资源的严重浪费。A large number of waste dry batteries not only cause serious pollution to the environment and harm to human health, but also lead to a serious waste of resources.
目前废旧干电池的回收处理方法主要分为三类，即人工分选法、火法和湿法。人工分选法是将回收的废旧干电池先进行分类，人工分选出碳棒、铜帽、锌皮及各种产品残留物，并分别采用相应的方法予以处理，这种方法简单易行，但使用劳动力多，经济效益差，存在二次污染。火法是在高温下使电池中的金属及其化合物氧化、还原、分解和挥发、冷凝，有效地回收其中的汞、镉等易挥发物，但是技术要求高，空气参与作业造成二次污染，一次性投资大，能耗高，运行成本高。湿法处理技术是基于电池中金属及其化合物溶于酸的原理，将分类、破碎分选后的电池粉末浸泡于酸性溶液中，使目标组分溶于酸液中，然后经过过滤，弃去有机电解质及隔膜杂质，调节所得含目标组分的滤液的pH值，将Al、Fe等微量元素以氢氧化物的形式除去，利用化学沉淀、电化学沉积、离子交换或萃取分离的方法使目标组分以纯金属或金属盐的形式得以回收，此方法工艺流程冗长复杂，回收后电解液含有汞、镉、锌等重金属，污染严重，能耗高。At present, the recycling and processing methods of waste dry batteries are mainly divided into three categories, namely manual sorting method, fire method and wet method. The manual sorting method is to classify the recovered waste dry batteries first, manually sort out carbon rods, copper caps, zinc skins and various product residues, and use corresponding methods to deal with them. This method is simple and easy, but The use of labor is large, the economic benefit is poor, and there is secondary pollution. The fire method is to oxidize, reduce, decompose, volatilize, and condense the metals and their compounds in the battery at high temperature, and effectively recover volatile substances such as mercury and cadmium in them, but the technical requirements are high, and the air involved in the operation causes secondary pollution. The one-time investment is large, the energy consumption is high, and the operating cost is high. Wet treatment technology is based on the principle that metals and their compounds in batteries are soluble in acid. Soak the sorted, crushed and sorted battery powder in acid solution to dissolve the target components in acid solution, then filter and discard Organic electrolyte and diaphragm impurities, adjust the pH value of the obtained filtrate containing the target components, remove Al, Fe and other trace elements in the form of hydroxides, use chemical precipitation, electrochemical deposition, ion exchange or extraction separation methods to make the target The components can be recovered in the form of pure metal or metal salt. The technical process of this method is long and complicated. After recovery, the electrolyte contains heavy metals such as mercury, cadmium, and zinc, which causes serious pollution and high energy consumption.
中国专利公开号CN200410102799.1，公开日2006年7月5日，发明创造的名称为利用烧结工艺处理废旧电池的方法及系统，该申请案公开了一种利用烧结工艺处理废旧电池的方法，其不足之处是利用水洗过滤系统，回收锌、钠、钾金属元素，二次污染严重，工艺流程较为冗长，能耗高，运行成本高。Chinese Patent Publication No. CN200410102799.1, published on July 5, 2006, the name of the invention is a method and system for treating waste batteries by sintering process. The application discloses a method for treating waste batteries by sintering process. The disadvantage is that the water washing and filtering system is used to recover zinc, sodium, and potassium metal elements, resulting in serious secondary pollution, lengthy process flow, high energy consumption, and high operating costs.
到目前为止，尚未出现利用转底炉工艺处理废旧干电池的方法。So far, there is no method for using the rotary hearth furnace process to process waste dry batteries.
